Identification
A long white day is followed by a Doji that gaps in the direction of the trend. The third day is a black day that closes in the bottom half of the white candle.

The Psychology
In an uptrend or within a bounce of a downtrend, the market gaps up but does not continue its upward movement. Instead enough bears step up to bring supply and demand back into equilibrium and the stock churns in place. This is the bearish Doji Star formation. A subsequent follow through gap down that closes below the midpoint of the white day completes the pattern and confirms the reversal.

We consider this to be a risky trade. ET was rallying on strong volume when it formed a bearish Evening Doji Star formation that ended the uptrend and began a downtrend. We consider this to be a risky trade even though Evening Doji Stars carry a high reliability rating. A safer play would be the formation of this pattern at resistance.
